The Government stands committed to addressing the global collective action problem of climate change through multilateralism and resolute domestic actions, including, improving the understanding of the subject through various research endeavours. The Government is fully aware that research and knowledge generation are critical aspects of the fight against climate change.
Climate change is a cross-cutting issue spanning various Ministries/ Departments and institutions under them. Research on climate change is mainly sponsored by the Department of Science and Technology, Ministry of Earth Sciences , Ministry of Environment, Forest and Climate Change, Indian Space Research Organisation , Ministry of Agriculture and Farmers Welfare, and Council of Scientific and Industrial Research. Sectoral aspects of climate change are also studied by different Ministries/Departments concerning sectors like agriculture, water resources, human health, power, renewable energy, transport, urban issues / development, etc. Further, a large number of universities and government research institutions such as the Indian Institute of Technologies , Indian Institute of Science , Central and State Universities and their departments also carry out climate change related research.
Indian National Centre for Ocean Information Services , an autonomous institute of MoES has acquired the baseline Airborne Lidar Terrain Mapping  elevation data from National Remote Sensing Centre  under ISRO for the Tsunami Inundation modelling and vulnerability mapping. This data is available for the mainland Indian coast up to two kilometres from the coast and would be used for predicting the sea-level rise.
As part of Indian Tsunami Early Warning System, INCOIS has established a real-time network of 36 tide gauges at different locations along the Indian coast to monitor the tsunami waves and provide timely advisories. It has established 4 tide gauges in Andhra Pradesh at the following locations.
